Our canine companions get cancer at relatively the same rate we do; our furry felines somewhat less. And with that diagnosis comes just as much concern. At GVS, cancer and compassionate care go hand-in-hand. From diagnosis to treatment, the overriding goal of our comprehensive Oncology department is comfort and quality of life. The expertise of our board-certified medical oncologist, Dr. Terrance Hamilton, guides the management of the patient. Dr. Jennifer Arthur is our radiation oncologist -- specially trained in the treatment of cancer and pain management through the use of radiation therapy. GVS not only has the most modern technology, including a linear accelerator, it also has the capability of a multi-modality approach, which means combining traditional therapies for optimal outcomes. Many types of cancers respond favorably to specific treatments, and research continues to identify new treatments like the DNA vaccine for melanoma.

  • Early diagnosis has a significant effect on the success of treatment. GVS has a CT and MRI technology on site for precise diagnosis. Both the CT Scan and MRI allow visualization of different parts of the body in great detail and contrast. CT is particularly useful in aiding the diagnosis of nasal disease, middle/inner ear disease, neurologic disease and certain bone disorders. MRI is utilized to diagnose brain disorders, spinal cord disease or difficult to diagnose soft tissue injuries.
  • Chemotherapy uses combinations of different drugs in the form of pills, injections, and IV infusions to control the growth of tumors. This method of treatment may be recommended for cancer that has spread, tumors that occur at more than one site, tumors that cannot be removed surgically, or for tumors post-operatively. Generally, animals tolerate chemotherapy better than humans, usually with fewer side effects.
  • Surgery remains a common and valuable treatment for benign and malignant cancers. It is often recommended to remove as much of the tumor as possible, or to explore an area to evaluate the tumor itself.
  • Radiation therapy is the use of a directed and focused beam of radiation to damage and/or kill cancerous cells in a localized area. It can be used as the sole treatment or as part of a multimodality treatment course for either local tumor control or palliative therapy for pain control and relief from symptoms caused by the tumor.
  • Biopsies, bone cores, bone marrow aspirates and ultrasound are procedures used to diagnose and stage (determine the advancement) the cancer to establish the best course of treatment.
  • Currently, GVS is the only facility in Atlanta offering the vaccine for melanoma.
